Don't skip salting the zucchini – it's the difference between lasagna and lasagna soup. Use full-fat ricotta and low-moisture mozzarella to avoid excess water. Let the lasagna rest before cutting to allow the layers to set. For make-ahead, assemble unbaked and refrigerate up to 2 days, or freeze for up to 3 months.
